HEATER.

Specification of Letters Patent.

, Patented Dec. 30, 1919.

Application filed December 14, 1918. Serial 110. 266,770.

the invention is to provide means whereby the fumes and foul air fromthe burner may be carried ofi without causing a loss of heat, and afurther object of the invention is to provide for a constant supply offresh air to the combustion chamber Without liability of the flameworking back into the air supply plpe.

The stated ob ects of the invention and other objects which willincidentally appear in the course of the following description areattained in such an apparatus as is illustrated in the accompanyingdrawings, and

the invention resides in certain-novel features which will beparticularly pointed out in the claim following the detaileddescription.

In the drawings:

Figure 1 is a perspective vie-w of a heater embodying my invention;

Fig. 2 1s a horizontal section on the line 2-2 of Fig.1;

Fig. 3 is an enlarged vertical section.

in carrying out my invention I employ an outer casing or shell 1 whichis open at its lower end and provided at said end with feet or othersupports 2 whereby it will be supported in spaced relation to the fioor.The upper end of this casing is preferably somewhat contracted, as shownat .3, and from said end a heating flue 4 may pass to the room or roomsto be heated. Within the outer casing 1 and in spaced relation theretois an inner casing or drum 5 which is supported by brackets 6 extendingbetween the lower ends of the two casings whereby an air space 7 will beprovided to communicate with the flue 4. The upper end of the innercasing or drum 5 is closed by a plate 8 which will preferably be castmetal so as to obtain the desired resistance to warping while the otherparts of the apparatus will preferably be constructed of sheet metal soas to facili tate the dissemination of heat and also minimize the costof manufacture.

tion chamber, and from it a plurality of We ti'cally spaced outlet pipes9 lead into a fume flue 10 which will generally extend to some pointoutside the building. Upon the inner surface of the drum are shields or.deflectors 11 which are secured at. their respective lower ends to'thewall of the same and extend upwardly in spaced relation to said wallover the inlet ends of the flues 9. The obnoxious fumes rising from thegas burner will be carried off through the flues 9 and 10 but will beprevented from passin directly into said flues by the shields or deectors 11 so that hot fumes must pass to and over the upper edges of thedeflectors in order to enter the escape flues. All the obnoxious odorsand gases will thus be permitted to escape without any excessive loss ofheat. An air supply pipe 12 is providedat one side of the heater and hasits upper end 13 extended through the walls of the inner and outercasings, and'fresh air necessary to support combustion will thus be fedconstantly to the combustion chamber. To prevent the flame and heathacking into the air supply pipe, a shield or deflector 14 is secured tothe wall of the drum below the outlet end of the air The upper. portionof the drum constitutes a combus-- pipe and extends up over thesame inspaced Which-passes below the lower ends of the drums or casings and isturned upwardly to form a nozzle 16 which will discharge the fuel into asleeve or cylinder 17 having a conical screen 18 over its upper end, anda screen 19 is secured in said sleeve or cylinder a slight distancebelow the upper end thereof so that the gas cannot escape too rapidlyand will be subdivided into a large number of very finestreams whichwill readily iignite above the conical screen and produce a arge blueflame in the combustion chamber which will give ofl an intense heat froma very small quantity of fuel. The nozzle 16 may be of any desiredconstruction and may be provided with an air mixer 20 so that the fuelwill be diluted prior to combustion.

The lower end of the inner casi or drum and of the burner cylinder 17Wlll also be open, and the said cylinder will be supported from theinner casing or drum by spaced rods or brackets 21, similar rods orbrackets 22 being utilized to support the mixer 'within the burnercylinder.

A door 23 may be provided upon the outer casin to give access to theburner when cleaning orrepairing of the same may be necessary. Thedoorframe will, of course,

. vice by the use of which the heat from a gas be constructed as shownat 24 so as to prevent the fresh air rising between the casings frompassing into the combustion chamber,

or the gas laden air in the drum passing into the space between thecasings: hence the heated air passing up the flue 4 will be free of allobnoxious elements.

It will be readily seen from the foregoing description, taken inconnection with the accompanying drawings, that I have provided anexceedingly simple and inexpensive deburner will be utilized in a highlyefficient manner to heat one or more rooms. None of the noxious vaporsgenerated bythe combustion of the gas will be permitted to pass off withthe air which is to be admitted into the ieaeese upper end, .and theinner casing constituting a drum having a combustion chamber within itsupper portion and its upper end closed, an air supply pipe passingthrough both casings and opening into said combustion chamher, a shieldover the inner end of said pipe,

fume outlet fiues opening at difl'erent heights from said chamber andpassing through both casings, a deflector over the inner end of each ofsaid fiues, a gas burner nozzle above the lower end of both casings, anda cylinder around the nozzle within the lower portion of said drum andterminating short of the combustion chamber for directing mixed.- airand gas upward past both deflectors and into said combustion chamber.

In testimony whereof I affix my'signature.
